  80 E 11

is a German BOS radio, used by Public Service.


It is an 11-channel- UHF- Radio, built by Telefunken. It mostly had a vehicular use. Size was small and power consmption was very low for those times. Using an optional power supply, the radio could also be used as a fixed station. It could be used in cars with 6 or 12 V.

The radio was sold in two versions that also looked different from the outside:

  • Duplex: with built in band combiner and one call pushbutton    (collection's radio);
  • Simplex: with built in antenna switch, three more call pushbuttons; a    squelch that can be switched off; this radio can also operate a    selective call set.

    Frequency range:
    68 ... 87.5 MHz
